Example Question #1 : Identifying Punctuation Errors: Commas For Introductory Or Interrupting Phrases

Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.

If you decide to go to the beach make sure to wear sunscreen to protect your skin! No error

Possible Answers:

to protect your skin!

If you decide

to wear

No error

to the beach make sure

Correct answer:

to the beach make sure

Explanation:

The phrase "If you decide to go to the beach" is an introductory phrase, and all introductory phrases need to be set apart from the rest of the sentence by a comma. So, after being corrected, the sentence would read, "If you decide to go to the beach, make sure to wear sunscreen to protect your skin!"

Example Question #2 : Identifying Punctuation Errors: Commas For Introductory Or Interrupting Phrases

Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.

Daisy and her sister, Margot, shared a large family but a special relationship; even among their numerous older and younger sisters, Margot, and Daisy had a special bond. No error

Possible Answers:

No error

among

sisters, Margot, and

her sister, Margot,

relationship; even

Correct answer:

sisters, Margot, and

Explanation:

Because the sentence states that Margot is not Daisy's only sister, the commas and which frame her name in "their numerous older and younger sisters, Margot, and Daisy" are incorrect. The comma that sets apart Margot's name at the beginning of the sentence ("Daisy and her sister, Margot, shared") is correctly used, because here, Margot is being specified as Daisy's sister in an appositive phrase that renames "her sister" as "Margot."

Example Question #3 : Identifying Punctuation Errors: Commas For Introductory Or Interrupting Phrases

Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.

Despite disinterest

student government

No error

Shindra the treasurer,

Correct answer:

Shindra the treasurer,

Explanation:

"The treasurer" here is an appositive: it renames or restates Shindra in different words, and it should be surrounded with commas. The correct sentence should be: "the students voted Shindra, the treasurer, president . . ."

Example Question #4 : Identifying Punctuation Errors: Commas For Introductory Or Interrupting Phrases

Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.

Possible Answers:

manager, the entire team

without interruption

immediately; the

At the insistence

leader however,

Correct answer:

leader however,

Explanation:

The word "however" here is considered a non-essential phrase: it can be removed, leaving a complete sentence. So it must be surrounded with commas: "The project leader, however, continued . . ."

Example Question #1356 : Psat Writing Skills

Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.

Perdita the lost princess, was found and raised by a shepherd. No error

Possible Answers:

found and raised

by a shepherd.

was

No error

Perdita the lost princess,

Correct answer:

Perdita the lost princess,

Explanation:

Commas should be used to set off the phrase "the lost princess," as it is in apposition to (gives a description of) the subject Perdita, but the sentence still makes sense without it. So, "Perdita the lost princess," contains the sentence's error, and the sentence should read, "Perdita, the lost princess, was found and raised by a shepherd."
